This is a rather common symptom when confronted with the cabalistic mystery of The Hole and The Array :P

I think the manual should bee more specific of what a t[key]= nil really means
(A) t[key] element exists and is set to nil
(B) t[key] element is absent from the table/array and has not material value

(B)... but... in practice... this doesn't make any difference to the outcome... t[key] would return nil in both case...
